If the mail server is that accessible to any machine behind the firewall, then
that in itself is a problem.

But at that level of compromise there are untold things they could do that
would be easy, silent, and probably less noticeable than passing infected
messages. This would just add one more, relatively minor possible attack to an
infinitely long list.

The only safe thing to do at that point is wipe the drive and start
over.

I've seen a couple of odd-ball problems.  My take is if it's not a VERY temp
file intensive task, leave 8.3 on.

Not really an issue.  F-Prot never touches the LFN that imail sees.

Imail is never aware of the filenames Declude passes to the command line
scanner, and the scanner is never aware of the queue filename. Imail passes
the queue file to Declude, Declude does it's stuff then either passes the
clean queue file on to SMTP32,  or quarantines the queue file and sends it's
notices.

The only issue is that Declude currently unpacks attachments into a temp
directory named "\whatever\path\queuefilename.vir"  When Declude passes the
now longer directory name to the scanner,  the DOS scanner(s?) can't deal with
it.  Declude could decide to roll it's own 8.3 compliant temp directory names,
and imail wouldn't care.

F-prot never touches the queue file, and the queue filename is never changed
(outside of the standard imail locking mechanisms which are handled by
Declude).

For this to cause problems, ipswitch will have to FUNDAMENTALLY change the
only published hook into the SMTP processing stream.  Declude would not be the
only thing they would break.
